T0 all whom t may concern.'

Be it known that I, JOHN C. UKENA, a citizen of the United States, residing at Golden City, in thecounty of Barton and State of Missouri, have invented certain new and useful Improvements'in Motion-Transmitting Mechanism, of which the following is a specification. g 4 j This invention relates to mechanism for transmitting motion, and its ob]ect is to provide an oscillatory lever which is actuated by an escapement Wheel and operatively connected to la shaft by means of a crank and pitman connection, whereby the oscillations of the lever are converted into a rotary movement of 'the shaft.

Novel means are also provided for overcoming the dead center..

These objects areattained by means of a combination and arrangement of parts to be hereinafter described and claimed, reference being had to the accompanying drawing, in which- Figure l is an elevation of the mechanism, and Fig. 2 is a plan view of'a pawl-andratchet device.

Referring specifically to the drawing, 4V

denotes a suitable base or frame which supports the mechanism. On the base are bearings 5 in which is journaled a shaft 6 carrying an escapement wheel 7 having studs 8 on its face. Coperating with the escapement wheel is an oscillatory lever 9 having pallets 10 at its respective ends which extend into the, path of the studs, and are engageabley alternately by said studs, whereby the lever is oscillated. The base 4 has suitable bearings 11 supporting a shaft 12 on which the lever is fulcrumed intermediate its ends.

In bearings 13 mounted on the base 4 is journaled a shaft 14 having a balance wheel 15, and a crank 16, which latter has a pitman connection 17 with one endv of the lever 9, whereby the oscillations of said lever impart a rotary movement to the shaft 14. The machinery to be driven is belted or otherwise connected to the shaft 14.

The shaft 6 of the escapement wheel 7 is driven by a weight or other motor. A gear wheel 18 is shown which is operated by ratchet levers 19 which are fulcrumed on the shaft 20 of the gear wheel and carry spring-pressed pawls 21 engaging the teeth of said wheel. 'Io the free ends of the levers are connected weights 22 which are elevated by any suitable power and then allowed to specification of Letters Patent. i f

drop, whereby the wheel 18 is driven. The

ratchet. levers operate in alternate order, and the gear wheel is thus given a prac.A ticallyfcontinuous rotary motion. `4Agtrain of gears connects the ratchet gearl to a pinion 23 on the shaft 6. The width of the gear wheel is suflicient to accommodate the pawls 21 of two levers 19. The pawl ofthe third lever 19 engages teeth 18a on one face of the-` gear wheel. l

- Returning to the escapement mechanism, a means is provided for holding the wheel 7 stationary during Vthe period of time the crank 16 is passing the dead center. This; is

necessary'for the reason that a continuous uninterrupted rotary motion of the wheel 7 would not result in a rotary motion of the shaft 14, but such motion of the wheel 7 would merely rock the crank 16 back and forth, with a corresponding'motion ofthe shaft 14. However, by momentarily arresting the motion of the wheel 7 when the crank is at the dead center, the momentum stored up in the balance wheel 15 carries the crank over the dead center. The wheel 7 is then released and one of the studs 8 strikes one of the pallets to oscillate the lever. There'is suiiicient space between the studs to permit the slight swing of the lever when the wheel is being held stationary and the crank is passing the dead center.

The holding mechanism comprises a slidel y 1. The combination of an oscillatory lever, .n n a rotary member having means for oscillating the lever, driving means for said member, a shaft, a crank on the shaft, a pitman connection between the crank and the lever,

and means for arresting the movement of v the aforesaid rotary member as the crank passes the dead center.

2. The combination of an escapement wheel, an oscillatory lever having pallets coperating with said wheel, a shaft, a crank on the shaft, a pi'tman connection between the crank and the lever, driving means for the escapement Wheel, and means for arresting the movement of said wheel as thecrank passes the dead center.

3. The combination of an oscillatory lever, a rotary member having means for oscillating the lever, driving means for said member, a shaft, a crank on the shaft, a pitman connection between the crank and the lever, an eccentric on the shaft, ay slide for arresting the movement of the aforesaid rotary member as the crank passes the dead center, and an actuating connection between the eccentric and the slide.

ei. rlhe combination of an escapement wheel having studs on its face, an oscillatory lever having pallets extending into the path of the studs, a shaft, a crank on the shaft, a pitman connection between the crank and the lever, driving means for the kescapement wheel, an eccentric on the shaft, a slide movable into and out of the path of the studs of the escapement wheel for arresting the movement of said wheel as the crank passes the dead center, and an actuating connection between the eccentric and the slide.

5. The combination of an escapeinent wheel, an oscillatory lever having pallets cooperating with said wheel, a shaft, a crank on the shaft, a pitrnan connection between the crank and the lever, driving means for the escapement Wheel, an eccentric on the shaft, a slide for arresting the movement of the escapement wheel as the crank passes the dead center, and an actuating connection between the eccentric and the slide.

In testimony whereof l aiEX my signature in presence or two witnesses.
